The news — which was first broken by Korean outlet OBS — is a major blow to the group, who have only just debuted as a trio after members Thunder and Lee Joon left in November 2014.

G.O’s vocal issues first became known after he was rushed to hospital on June 11 following his throat closing up after an appearance on SBS Power FM’s Cultwo Show. At the time it was reported that the 27-year-old suffered from polyps on his vocal chords.
